Q. We're placing a concrete slab on metal decking, and the plans require welded wire fabric to be supported by chairs. Because the chairs are likely to be dislodged by workers during placement, we're trying to convince the designer that we can pull the fabric into the correct position with hooks. Does any publication recognize this as an allowable method for positioning welded wire fabric?
A. We don't know of any current publication that suggests welded wire fabric can be hooked into place. We agree that chairs are likely to be dislodged, and, depending on the wire size and spacing, the fabric is also likely to be pushed out of position by workers walking on it. However, we don't believe hooking the fabric is the answer to the problem, primarily because the worker doing the hooking will find it difficult to control fabric location.
